UNIVERSAL JOINT.

Specification of Letters Patent.-

Patented Sept. 10, 1918.

Application filed May 23, 1918. Serial No. 236,183. d

.To all whom it may concern:

' Be it known that I, GEORGE F. SEvnRs, a citizen of the United States,residing at Centerville, in the county of Appanoose and State of Iowa,have invented certain new and useful Improvements in. Universal Joints,

of which the following is a specification,

ig. 2 is a front view in elevation showing one section of the body of myjoint, and Fig. 3 is a vertical sectional view of the section shown inFig.2.

Fi 4 is a view in rear elevation of the' sectidn shown in Fig. 2.

Fig. 5 is a view in elevation of the inner end of one of the shafts.

Fig. 6 is a view in elevation of'the key plate, while Fig. 7 is an edgeview of the same. I

Referring to the drawings by numerals, 1 designates the body of my oint,which body comprlses a pair of similarly constructed sections 22, eachsection 2 is provided with an annular flange 3, and extending throughthe abutting flanges 3 are suitable fastening means, as bolts 4.

My improved joint comprises two sectional structures of which eachsection 2, of-

body 1, is a part thereof. It will only be.

necessary to describe one of the sectional structures, as the other is aduplicate.

The section 2 of the body, is substantially semi-spherical in shape andis'provided with slots 5, extending substantially longitudinallythereof, and in these slots 5, are'positioned the spurs 6 on the innerend of shaft 7. The extreme inner end of each shaft 7,

is rounded as clearly seen in Fig. 1', and the inner end of each spur 6is rounded in the same are of a circle as the inner end of shaft 7, sothat shaft 7 can have a relatively free swinging movement in largeaperture 8 formed in the body 2.

Each face 2 is provided with comparatively wide sockets 9, on theabutting sectlons 2, that register for receiving the double beveled ends10, of the fingers 11 of the key plate 12. The key plate 12 is flat onboth sldes at 13, so as to provide smooth bearing faces for the innerends of shafts 7. Each finger 11 is beveled transversely at 14, toreduce the weight of the device. By reason of the form of sockets 9, andthe beveled ends 10 of fingers 11, the plate is securely held in themiddle of my jolnt and spaces the inner ends of shafts 7 apart.

On each shaft is a closure cap 15, which cap 15, is provided with agasket or rubber r ng 16, bearing upon the surface of section 2 ofFig. 1. Locking nuts 17 arethreaded upon the threaded portion 18 ofshaft 7,

and interposed between the inner locking nut and the outer end of theslidable cap 15, 1s a coll spring 19, which normally holds the slidingcap 15 pressed against the section 2; gasket or ring 16 forms aneflicient closure for preventing dirt or moisture entering the body 1 ofthe joint. Upon carefully examining the drawing it will further be notedthat each section 2 is provided with ',narrowbeveled edges'20, whichedges 20 permit a free movement of the shaft 7 in each section 2, byallowing the portion 20 of the inner rounded end of each shaft 7 to turnfreer inthe section. I

From the foregoing description and the accompanying drawing, it' will beunderstood that I have produced a Very eflicient device, and I also wishit to be understood that I reserve the right to make certain alterationsin my joint as will fairly fall within the scope of the appended claims.

What I claim is: I

1. In a device of the class described, the

combination of a bodv formed of sections,

said sections provided with meeting edges, said sectlons provided withregistering sockets in their meeting edges, a key plate provided withfingers resting in the registering sockets of vthe sections of the body,and shafts extending into said body at opposite sides of the key plate.

2. In a device of the class described, the combination of a sectionalbody, said body provided with beveled portions constituting sockets, akey plate provided with fingers, each finger being doubled beveled onits outer end, said key plate being provided with fiat central faces,the double beveled ends of the fingers fitted in said sockets, and

shafts extending into said body and positioned contiguous to the flatcentral faces of the key plate.

'3. In a device of the class described, the

combination of abody comprising two imilarly constructed sections, eachsection provided with a flat outer face and with comparatively widesockets formed in said outer face, said section being also'provlded withcomparatively long longitudinal-extending .sockets, a shaft extendinginto each section, the inner end of each shaft provided with side-spurs,each spur being seated in a longitudinal socket, the inner end of eachshaft and the inner end of each spur being permitting. the rounded endsof the shaft to have a rocking action over said faces.

In testimony whereof I hereunto afiix my signature.
